FIREARM.

Specification of Letters ratcnt.

Patented Apr. 27, 1915.

Application filed November 12, 1914. Serial No. 871,652.

To all whom it may concern:

Be it known that I, CLARENCE A. Goo- SHALK, a citizen of the United States, residing at Philadelphia, county of Philadelphia,

State of Pennsylvania, have invented a new and useful F irearm,'of which the following is a specification.

My invention relates to a new and useful improvement in fire arms and cons1sts of novel means for connecting the top rib with the barrel thereof.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in the accompanying drawing certain forms thereof which will give in practice satisfactory and reliable results, although it is to be understood that changes may be made and the arrangement var1ed which will come within the scope of the claims.

Figure 1 is a side elevation of a portion of a barrel and af'portion of the top rib, embodying my invention. Fig. 2 is a top plan view thereof. Fig. 3 is a sectional view on line ww Fig. 1. Fl 4 is a side elevation, on a reduced scale, 0 a portion of a barrel and top rib and showing a portion of the frame and stop in dotted lines. Fig. 5 is a partial elevation partial sectional view of a portion of a barrel and top rib, showing another embodiment of my invention. Fig. 6 is a sectional view on line yy Fig. 5.

Heretofore it has been customary to rigidly connect the top rib of a fire arm with the barrel thereof throughout the length of the rib, or at intervals thereof, and, due to the expansion and contraction of the barrel longitudinally, this has been found in some instances either to distort the top rib or else to cause the standards to break away from the barrel or from the top rib. My invention is designed to overcome this and to provide means whereby the top rib is connected at one end rigidly with the barrel and at a suitable point or points is movably connected therewith in order to permit the expansion and contraction of the said barrel without effect upon the top rib.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawin 1 designates a ortion of the barrel of a re arm and 2 the breech end thereof. At a suitable point or points on the barrel I provide standards 3,

one end of each of which is rigidly connected with the barrel and the other end of which is movably connected with the rib, although this arrangement may be varied, if desired. As here shown, the standards 3 are brazed or otherwise secured in any suitable manner to the barrel 1, and are movably connected with the top rib 4. This movable connection may be accomplished in many different ways, and in the drawings I have shown each standard provided with means for movable engagement with the top rib 4. As here shown, I have provided a groove or slot 5 in the standard which is preferably'T-shaped. The top rib 4 is suitably connected to the barrel adjacent the breech end 2 by soldering, electrowelding, brazing, or otherwise, and at suitable points on the rib 4, corresponding with the standards 3, I provide projecting members, here shown as headed pins or links 6, each of which is suitably secured to the rib and movably connected with a standard 3, said pins being shaped to engage with and move in a slot 5 in a standard 3, whereby it will be understood that while the rib is pre vented from improper displacement, longitudinal movement is permitted between the barrel and rib and breakage of the parts is prevented.

Another embodiment is shown in Figs. 5 and 6, wherein I have pivoted each of the links 7 at one end 8 to the rib 4 and at the other end 9 to a standard 3, with the same result as above described. It will be understoodthat the standard and rib are suitably formed to accomplish the desired results.

It will now be apparent that I have devised a novel and useful construction of a fire arm which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described preferred embodiments thereof which will give in practice satisfactory and reliable results, it is to be understood that the same are susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a device of the character stated, a barrel, a top rib having one end rigidly connected therewith, a standard rigidly connect- 15 standards connected with said ed with said barrel, and means on said rib adapted to inovably engage with said standard to hold the rib in position and to permit longitudinal movement between the parts.

6 2. In a device of the character stated, a

barrel, 2, top rib having one end rigidly connected with said barrel, and a plurality of standards rigidly connected with said barrel and in movable engagement with said 10 rib to permit longitudinal movement between the parts;

3. In a device of the character stated, a barrel, a top rib having one end suitably connected with said barrel, a plurality of barrel, projections on said rib having movable engage- CLARENCE A. GODSHALK.
